Mail-in voting is rigged
The claim that mail-in voting is systematically fraudulent or rigged is not supported by evidence. Decades of data from states that conduct elections primarily by mail show fraud rates that are infinitesimally small, and multiple independent studies find no systematic evidence of mail ballot fraud.
What we know
Mail-in and absentee voting has been used in U.S. elections since the Civil War. Five states, Oregon, Washington, Colorado, Hawaii, and Utah, conduct nearly all elections entirely by mail. None has experienced a voter fraud scandal that has affected any electoral outcome since adopting this system.
The Brennan Center for Justice notes that Oregon has sent more than 100 million mail-in ballots since 2000 and documented only about a dozen proven fraud cases, 0.00001% of all votes cast. A Heritage Foundation analysis, which actively documents voter fraud cases, identified only 207 cases of absentee ballot fraud out of 1,277 total voter fraud cases across decades, representing 16% of all documented fraud cases, with the vast majority related to in-person voting.
Multiple academic studies using quantitative methods to detect systematic fraud in recent elections have found none. A 2021 peer-reviewed study in the Proceedings of the National Academy of Sciences found all statistical claims of mail-ballot fraud in the 2020 election either were consistent with normal election dynamics or were based on analytical errors. Political scientists broadly agree that voter fraud in contemporary U.S. elections is extremely rare.
Mail ballots include multiple security layers: signature verification against voter rolls, personal identification information matching, tamper-evident envelopes, tracking systems, and post-election audits. The penalty for mail ballot fraud is up to five years in federal prison. The known case of mail ballot fraud affecting an election outcome in recent years, the 2018 North Carolina 9th Congressional District case, involved a Republican political operative and was detected by the existing system, resulting in the election being overturned.
Common claims
- Mail-in voting leads to widespread, systematic fraud.False, fraud rates are documented at less than 0.0001% and no all-mail state has experienced a fraud scandal since adopting the system.
- Signatures on mail ballots are not verified.False, most states use signature matching against voter registration records for every mail ballot.
- The 2020 election mail ballot expansion created large-scale fraud.False, multiple court rulings, audits, and the PNAS study found no evidence of systematic fraud.
- Mail-in voting has fewer security safeguards than in-person voting.Mixed, mail ballots are more vulnerable to certain forms of fraud (coercion, third-party tampering) but have their own multi-layer verification systems.
